Assembly and Disassembly
Proceed with caution. There is danger of personal injury.
Never disassemble the valve screws without reading the instructions thoroughly.
Assembly and disassembly of the valves / actuator must only be carried out by qualified staff.
When assembling the diaphragm it is very important to comply with the sequence of steps,
as otherwise, the diaphragm may be damaged. In particular, do not fully tighten the body
until the diaphragm is in the closed position. Otherwise, the diaphragm may deform and be
damaged when the valve is closed.
7.1.
DISASSEMBLY / ASSEMBLY OF THE MANUALLY ACTUATED VALVE
Disassembly
1.
Turn the actuator handle (10) so that the
valve is in the open position.
1.
Unscrew the Allen screws (23) from the
actuator (10).
2.
Remove actuator (10) from the body (01).
3.
Turn the actuator handle (10) so that the
valve is in the closed position.
4.
Remove the diaphragm (05) from the
compressor (63).
Assembly
1.
Turn the actuator handle (10) so that the
valve is in the closed position.
2.
Attach the diaphragm (05) to the
compressor (63) so that the metal pin of
the diaphragm is inserted into the groove
of the compressor.
3.
Place the actuator (10) in the open-valve
position.
4.
Connect the body (01) to the actuator (10)
by screwing in the Allen screws (23) and
washers (25) without fully tightening the
screws (use fingers to screw in). So that
the body (01) remains fixed to the
actuator (10), but not yet completely tight.
5.
Almost fully close the valve to deflect the
diaphragm and fully tighten the screws.
Apply grease to the screws before
tightening, see chapter 6
Maintenance.
6.
See the tightening torque of the screws in
chapter 8
Technical Specifications.
The following tools are required to disassemble the valve.
•
Allen key 3mm for size nº1
•
Allen key 5mm for size nº2
•
Allen key 6mm for size nº3
•
Allen key 10mm for size nº4
